Background

The site is located at 731 Enger Rd. in Nazareth within Plainfield Township in Northampton County, Pennsylvania. The facility was established in 1972 as Hi-Pure Chemicals, Inc. The site consists of tract # 1 and tract # 2. The tracts are non-contiguous properties, and industrial activity was limited to tract # 1. Tract # 1 is approximately 360 feet by 650 feet and consists of a large manufacturing building/warehouse and an office building. Industrial activities conducted by the Olin Corporation began in 1984.
